Cowboys’ Tony Romo will miss rest of season because of collarbone injury

Dallas quarterback Tony Romo will miss the rest of the season with a small fracture in the same collarbone that previously sidelined him for seven games this year.

Cowboys owner and general manager Jerry Jones said on his radio show Friday that Romo’s left collarbone would not require surgery after getting hurt in the third quarter of Thursday’s 33-14 loss to Carolina. He didn’t need surgery after breaking the collarbone in Week 2 at Philadelphia, either.

It’s the third fracture in Romo’s non-throwing shoulder in his nine-year career as the Dallas starter. He missed most of 2010 after getting hurt against the New York Giants.

Romo was in his second game back after the Cowboys (3-8) lost seven straight without him. The Carolina loss was his first of the season.

Bills’ Kyle Williams out for season

Buffalo Bills defensive tackle Kyle Williams will undergo surgery on his left knee and miss the rest of the season.

Williams said he will need surgery for a meniscus injury. The 10-year veteran has been out since suffering the injury against the Cincinnati Bengals in Week 6.

Williams, 32, hoped to play through the injury, but was not making progress after six weeks of rest.

Revis still dealing with concussion

Cornerback Darrelle Revis will not play in the New York Jets’ game against the Miami Dolphins because he is still dealing with a concussion. He remains in the NFL’s concussion protocol and must be cleared by doctors before he can practice with the team.

“He’s doing a little better each day,” Coach Todd Bowles said Friday, “but not well enough for physical activity.”

Revis was injured during the Jets’ 24-17 loss at Houston last Sunday and has not practiced since. Bowles said the star cornerback comes to the facility for treatment in the morning and then is sent home.

Manziel may not be activated

Johnny Manziel’s demotion might include him not dressing for the game.

Browns Coach Mike Pettine said he hasn’t decided whether Manziel, who was stripped of his starting job this week, will be active for Monday night’s matchup against Baltimore.

Manziel was downgraded from starter to third string when a video surfaced of him partying during Cleveland’s bye week in an Austin, Texas, club.
